Re: octave and 'fixed' package: some issues

[YuHong]

 

Hello,

 

I am also on Ubuntu-11.04-64bit system.  I have built the most recent stable octave-3.4.2; so do not need to go back to earlier versions.  Build-from-source may not be very easy thing; so my experience could provide a not-too-bad example for your reference.

 

Best regards,

 

Hong Yu

Subject: octave and 'fixed' package: some issues

 

Hi,
I used octave 3.2.3 + fixed as it came in ubuntu distribution about one year ago. It worked very fine and I succesfully did some modeling.

1)
Now I had to upgrade ubuntu to the last version (11.04).
It is still possible to install octave and the fixed package from synaptic but when you call fixed from octave, you get this error:

fi_y = fixed(6,0,y)

error: `fixed' undefined near line 8 column 8

It is not clear to me what this means, because the fixed package is loaded and this command worked perfectly with the 3.2.3 version of octave.

Do you know if I am making any mistake ?

2)
I tried to install manually octave 3.2.3 from the tar file in a local directory.

I got this error while doing the make check:

........
 scripts/geometry/rectint.m ............................. PASS    9/9  
  scripts/geometry/tsearchn.m ............................ PASS    5/5  
  scripts/help/doc.m ..................................... PASS    1/1  
  scripts/image/contrast.m ............................... PASS    1/1  
  scripts/image/imread.m .................................octave: magick/semaphore.c:525: LockSemaphoreInfo: Assertion `semaphore_info != (SemaphoreInfo *) ((void *)0)' failed.
panic: Aborted -- stopping myself...
make[2]: *** [check] Aborted
make[2]: Leaving directory `/tools/octave/octave-3.2.3/test'
make[1]: *** [check] Error 2
make[1]: Leaving directory `/tools/octave/octave-3.2.3'
make: *** [check] Error 2

Do you know what is the cause of this ?
Attached I send you the log files of make check and of make.

3) Final question: does it still make sense to work with the fixed package ? To my understanding it will not be ported to 3.4.* versions of octave.

Thank you,
Kind Regards
Dario
